Anti-Wrinkle Injection Safety & Consent in the UK

Anti-wrinkle injections use a prescription-only injectable medicine available under several brand names in the UK, including Azzalure, Bocouture, and others. Under UK advertising rules — specifically the Human Medicines Regulations 2012 and guidance from the Advertising Standards Authority (ASA) — it is not permissible to promote prescription-only medicines by brand name to the public. For this reason, this guide uses the term “anti-wrinkle injections” throughout.

This guide is designed to help you understand the safety considerations, regulatory framework, and consent process involved in having anti-wrinkle injections in the UK. It is not a substitute for a clinical consultation, but it should help you ask the right questions and make a more informed decision about your treatment.

Regulation in the UK

The active ingredient is classified as a prescription-only medicine (POM) in the UK. This means it can only be prescribed by a qualified prescriber — a doctor, dentist, or an appropriately qualified nurse or pharmacist with independent prescribing rights. The prescriber must assess the patient before issuing a prescription, and they are clinically and legally responsible for that prescribing decision.

However, once prescribed, the actual injection of the treatment can legally be performed by someone who is not a prescriber. This has led to a range of practice models in the UK, some of which raise significant safety concerns. In some clinics, a doctor may prescribe remotely — sometimes via a brief telephone call or an online questionnaire — without ever physically examining the patient. The injection may then be performed by a practitioner with variable levels of training and experience. While not illegal, this model falls short of what most medical professionals would consider acceptable clinical practice.

The Advertising Standards Authority (ASA) regulates how anti-wrinkle treatments can be promoted to the public. Because it is a prescription-only medicine, it cannot be advertised by brand name to consumers. Clinics cannot offer promotions, discounts, or special offers that specifically name the product. Advertising should focus on the treatment and its outcomes rather than promoting a specific product. Clinics that advertise branded deals or similar promotions may be in breach of these rules.

The Joint Council for Cosmetic Practitioners (JCCP) maintains a voluntary register of practitioners who meet its standards for training, insurance, and professional conduct. While registration with the JCCP is not legally required, it provides patients with an additional means of verifying a practitioner’s credentials. The JCCP also provides a register of approved clinics and educational institutions.

At present, there is no mandatory licensing scheme for non-surgical cosmetic practitioners in the UK beyond the existing requirements for prescribing. This means that, in practice, anyone can set up as a cosmetic practitioner and perform treatments that do not involve prescription medicines — including dermal filler injections — without any formal training, qualifications, or insurance. This regulatory gap has been widely criticised and there are ongoing discussions about introducing mandatory standards, but for now, the responsibility falls largely on patients to verify their practitioner’s credentials.

Common risks and side effects

Like all medical treatments, anti-wrinkle injections carry risks. Most side effects are minor, temporary, and resolve without intervention. However, more serious complications can occur, and it is important that you are aware of these before proceeding with treatment.

Common side effects

• Bruising: Small bruises at the injection sites are common and typically resolve within a few days to a week. Bruising can be minimised by avoiding blood-thinning medications and supplements before treatment, where clinically appropriate.
• Headache: Some patients experience a mild headache following treatment, particularly after treatment to the forehead area. This usually resolves within 24 to 48 hours.
• Temporary heaviness: Some patients notice a feeling of heaviness in the treated area during the first few days as the treatment begins to take effect. This typically resolves as the patient adjusts to the reduced muscle activity.
• Redness and swelling: Mild redness and swelling at the injection sites are normal and generally settle within a few hours.

Less common side effects

• Eyelid droop (ptosis): This is an uncommon but recognised side effect that occurs when the active ingredient migrates to affect the muscle that raises the upper eyelid. It is usually temporary and resolves as the effect wears off, but it can take several weeks. The risk can be minimised by correct injection technique and appropriate dosing.
• Asymmetry: Some degree of facial asymmetry is natural, and anti-wrinkle treatment may occasionally accentuate this. Asymmetry can usually be corrected with a small additional dose at a follow-up appointment.
• Eyebrow droop or elevation: Changes in eyebrow position can occur if the balance of muscle activity is altered by the treatment. This is usually temporary and resolves as the effect wears off.

If you experience any unexpected or concerning symptoms following treatment, you should contact your treating clinic promptly. Serious adverse events are rare but require immediate clinical attention. A reputable clinic will have protocols in place for managing complications and will provide clear aftercare instructions and emergency contact details.

Our approach to safety

At Berkshire Aesthetics, patient safety is the foundation of everything we do. Dr Selena Langdon is the prescriber for all injectable treatments and is directly involved in patient assessment, treatment planning, and clinical decision-making. She does not prescribe remotely for new patients, and every patient receives a thorough clinical assessment before any treatment is considered.

We operate a consultation-first model, meaning that new patients are always seen for a consultation before treatment. This consultation includes a detailed medical history, a clinical examination, and an honest discussion about what treatment can realistically achieve. We provide a cooling-off period between consultation and treatment, and we never pressure patients to proceed.

The clinic is registered with the Care Quality Commission (CQC), which means we meet recognised standards for healthcare provision and are subject to regulatory inspection. We have documented protocols for managing complications, including the emergency medications and equipment necessary to respond to serious adverse events.

We use only products sourced through authorised UK pharmaceutical distributors, ensuring that the medications used in your treatment are genuine, properly stored, and within their expiry date. We maintain comprehensive patient records, and all patients have access to clear aftercare instructions and a direct line to the clinic for any post-treatment concerns.
